Random Test Generation of Application Programming Interfaces

Cloud high quality API (Application Programming Interface) testing is essential for supporting the API economy. Autotest is a random test generator that addresses this need. It reads the API specification and deduces a model used in the test generation. This paper describes Autotest. It also address the topic of API specification pitfalls which Autotest may reveal when reading the specification. A best practice is to add an appropriate test to the regression once a problem is revealed and solved. How to do that in the context of Autotest's random test generation is covered.
